Abstract: Processes for limiting circulation of precipitates in a redox flow battery system are described. The processes include filtering the negative electrolyte, or the positive electrolyte, or both in one or more filters. The filter(s) can be located in the negative electrolyte loop, the positive electrolyte loop, or in both loops. Filtering can take place in normal operation; it can also take place during refresh cycles.

Abstract: A fuel cell system includes: a fuel cell stack; a fuel tank; a fuel pipe connecting the fuel cell stack and the fuel tank; a fuel regulator disposed in the fuel pipe and configured to regulate a flow rate of fuel gas to be supplied from the fuel tank to an anode; a fuel stop valve disposed in the fuel pipe; and a controller. The controller is configured to execute, when activating or stopping the fuel cell stack: a first process of opening the fuel stop valve and the fuel regulator; a second process of closing the fuel stop valve and the fuel regulator when an anode internal pressure reaches a predetermined first anode pressure; and a third process of outputting a signal indicating occurrence of fuel leakage when the anode internal pressure after a predetermined first period is lower than a predetermined second anode pressure.

Abstract: A method of operating a water electrolysis and electricity generating system includes, at a time of switching from the water electrolysis mode to the electricity generating mode, a water electrolysis stopping step, a purging step and an electricity generation starting step. In the purging step after the water electrolysis stopping step, an oxygen-containing gas is caused to flow from an oxygen-containing gas flow path to a first gas-liquid separator via an oxygen-containing gas introduction flow path, a first supply flow path, a first inlet port member, a first fluid flow path, a first outlet port member, and a first lead-out flow path. In the electricity generation starting step after the purging step, the cell member is caused to generate electricity based on a predetermined required load value.
